Quick Summary
After a commercial truck accident, first move to safety if you can, turn on hazard lights, and call 911 even if the crash seems minor. Get medical attention the same day, since injuries can appear hours or days later. Document the truck's USDOT number, carrier details, and the scene, then quickly request preservation of truck-specific evidence like electronic logs and camera footage.
The first hour after a commercial truck accident often shapes everything that follows. A crash with a semi-truck is different from a typical car wreck. Our guide to how federal trucking rules affect a crash and its aftermath explains what those rules mean for you. Knowing what to do first helps you stay safe and protect your claim.

The National Safety Council reports that 5,218 large trucks were involved in fatal crashes in 2024 (National Safety Council, Injury Facts on large-truck crashes). That scale of risk is why the steps below matter.
If you can move safely, get out of traffic. Turn on your hazard lights. Set out warning triangles or flares if you have them. Stay away from fuel leaks, downed power lines, and fire.
Check yourself and your passengers for injuries before you do anything else. Some injuries, like head trauma or internal bleeding, may not show right away.
Call 911 even if the crash looks minor. A police report creates an official record of how the crash happened, who was involved, and what the officer observed. Ask for emergency medical services if anyone is hurt.
Adrenaline can hide pain for hours or even days. Many people feel fine at the scene and develop neck pain, back pain, or headaches later. See a doctor the same day if you can.
Medical records also link your injuries to the crash. Without prompt treatment, an insurance company may argue that your injuries came from something else. Follow every treatment plan your doctor gives you, and keep copies of all bills and visit notes.
Good documentation makes a difference, but a commercial truck crash requires details a standard car-accident checklist never captures. Use your phone to record as much as you safely can, and write down details while they are fresh. Do this only from a safe position, behind a barrier, on the shoulder, or after police arrive, never while standing in a live lane. Recording the scene safely also helps you stay focused on immediate priorities, and the emergency accident recovery steps can help you think through what to do next.
Driver and vehicle information
Cargo, route, and delivery identifiers
People and conditions
Take wide shots and close-ups. Capture both vehicles, all damage, skid marks, traffic signs, lane markings, guardrails, and any debris. Photograph the truck's trailer, the cargo area, the cab, the wheels and tires, and any visible company markings, USDOT number, or MC number. Photograph your injuries as they develop over the following days, and keep the original files rather than edited or cropped copies.

Watch out: do not climb onto or under the truck, open trailer doors, or move cargo to get a better photo, cargo can shift, and hazardous materials may be present.
When it is safe, note the condition of the truck's tires, brakes, lights, reflective tape, and underride guards. These details can matter later because federal rules require periodic inspection and maintenance records for commercial vehicles, and a defect visible at the scene may connect to those records. Write down what you see in plain language rather than guessing at a cause.
Trucking companies often start building their defense quickly, and some of the most valuable evidence is on a clock. Electronic logging devices, engine control modules, dash cameras, and driver logs can be overwritten, deleted, or routinely purged within days or weeks. A prompt written preservation request, often called a spoliation letter, asks the carrier and other parties to hold that material before it disappears.
Send a written request to the carrier, the driver, and any other likely holder of records. Identify the crash by date, location, and the truck's USDOT number, and ask them to preserve the categories above. Keep a copy of the request and proof it was sent. A lawyer can send this on your behalf and follow up if a party does not comply.
Save any dash camera footage, phone photos, and text messages about the crash. Ask nearby businesses whether they have surveillance video and request that it be saved, since many systems overwrite footage quickly. Back up your files to a second location and keep the originals.
Watch out: posting crash details, photos, or injury updates on social media can give insurers material to use against you, and deleting posts later may not remove them from a carrier's records.
Record the carrier's name, the USDOT number, the motor carrier number, and the driver's full name and license number. Commercial trucks commonly display this information; confirm current display requirements with the FMCSA. Note the trailer number too, if visible. These identifiers are what let a preservation request reach the right company and the right records.
Some of the most valuable truck crash evidence is overwritten or purged within days or weeks, so these records are worth requesting early.
| Evidence | What it can show | Timing risk |
|---|---|---|
| ELD data | Driving time and duty status | Generally required to be kept, but can be purged |
| ECM / EDR data | Speed, braking, throttle in seconds before impact | Can be overwritten |
| Dash camera footage | Forward and driver-facing video | Often overwritten on a rolling loop |
| Driver logs and dispatch records | Time on duty and schedule pressure | Can be deleted or purged |
| Maintenance and inspection records | Equipment condition and upkeep | Subject to federal recordkeeping |
| Drug and alcohol testing records | Post-crash testing results | Check current FMCSA requirements |
Be polite and provide basic facts, such as your name and insurance information. Avoid guessing about fault, describing your injuries in detail, or agreeing to give a recorded statement before you understand your rights. Adjusters are trained to gather information that can reduce what they pay. Speaking with a lawyer before giving a detailed statement is often a wise choice.
Timelines vary widely. Our page on what to expect from a Nashville car accident case walks through the typical stages and timing. Simple claims may resolve in a few months, while cases with serious injuries, disputed liability, or a trucking company's involvement can take a year or more. Many cases settle without a trial, but some do go to court when insurers refuse fair offers. Our guide on whether insurance will settle or go to trial covers settlement rates and the factors that shape outcomes.

Move to safety if you can, turn on hazard lights, and call 911 to request police and emergency medical services. Do not leave the scene before police arrive, and avoid admitting fault. Check yourself and passengers for injuries, then start gathering information from the truck driver, including name, insurance details, and the carrier's name and DOT number. Photograph the vehicles and scene if you are physically able to do so safely.
Collect photos of both vehicles, property damage, skid marks, road conditions, traffic signs, and the surrounding area. Get the police report number, witness names and contact information, and the truck's license plate, DOT number, and trailer number. Save medical records, receipts, and a written journal of symptoms. Because trucking companies often retain electronic logs and dashcam footage only for a limited time, ask an attorney early about sending a preservation request.
Avoid guessing about fault, minimizing your injuries, or describing the accident in detail before you understand your injuries. Do not give a recorded statement or sign any release without reviewing it first. Stick to basic facts such as your name, the date, and the location. Insurance adjusters work for the insurer, and their goal is typically to limit what the company pays, so consult an attorney before you agree to speak at length about the crash.
Timelines vary widely based on injury severity, how quickly medical treatment is completed, the complexity of liability, and whether the case goes to litigation. Simpler claims may resolve in several months, while cases involving serious injuries, multiple parties, or disputed fault can take considerably longer. Filing deadlines apply to personal injury claims, so confirm the deadline that applies to your case with an attorney as early as possible.
